The oscilloscope is used to measure the time domain waveform of electrical signals. Here's how to use it: Connect to the circuit and ground; set the vertical gain and horizontal time base; trigger and analyze the amplitude, frequency, phase, and shape of the waveform; take advantage of advanced features such as FFT analysis, signal generator, and logic analyzer.

How to use an oscilloscope

An oscilloscope is an electronic instrument used to measure and display the time of electrical signals. domain waveform. Here's how to use an oscilloscope:

1. Connect the oscilloscope

  • Connect the oscilloscope's probe to the signal in the circuit you want to measure.
  • Use the oscilloscope’s ground probe to connect to the common ground terminal of the circuit.

2. Set the oscilloscope

  • Set the vertical gain of the oscilloscope so that the waveform is visible on the screen.
  • Set the horizontal time base and select the appropriate scan rate to display the complete waveform.
  • If necessary, adjust the trigger conditions to stabilize the waveform.

3. Analyze the waveform

  • Measure the amplitude, frequency and phase of the waveform.
  • Observe the shape of the waveform to identify any distortion or anomalies.
  • Use the oscilloscope’s cursor function to make precise measurements.

4. Advanced functions

  • FFT analysis:Convert time domain waveforms into frequency domain graphs.
  • Signal Generator:Generate sine waves and other waveforms to test circuits.
  • Logic Analyzer:Analyze digital signals.

Tip:

  • Be careful when using an oscilloscope and do not touch live parts of the circuit.
  • Always use proper probe attenuation to avoid damage to the oscilloscope.
  • Before taking measurements, please understand how the circuit works.
  • Practice more to become familiar with the operation of the oscilloscope.
